Layer Details
- Damask cover. A finely woven, durable fabric that's soft to the touch and doesn't retain heat, which means it should stay comfortable on warmer nights. It's built for long-lasting performance rather than a plush pillow-top feel.
- Soft White Fibres. Soft synthetic fillings that add a cosy layer over the firmer materials beneath. They're durable and resilient, designed to hold their shape over time rather than flattening quickly.
- Dual density polyester pad. Plush on one side and densely packed on the other, this pad reinforces the firm feel of the mattress. In practice it means you get a small amount of surface softness without losing that solid support underneath.
- Pocket Springs. 1,000 individual springs, each encased in its own cloth pocket, adapt to your movement independently. That means support is distributed to each part of your body, and your partner's movements are less likely to disturb you.

- The classic shared size: Two people sharing get 67.5cm each, and the 1,000 individual pocket springs mean your partner's turning is less likely to travel across that width to you.
- Fits typical UK bedrooms: We suggest a room of at least 2.6m x 2.8m, which most British doubles and second bedrooms can manage with furniture still in place.
- Firm support across the full width: The springs respond to each sleeper separately, so a heavier partner sinking in on one side won't tilt the surface under you.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet are stocked everywhere, so replacing bedding stays cheap and simple.
- Cooler nights for two: Two people warm a bed faster than one, and the damask cover doesn't retain heat, a quiet advantage on a shared mattress.
This size suits you if...
You share the bed every night and want firm support in a size that leaves room for wardrobes, drawers and bedside tables on both sides, or you sleep alone and like space to stretch, perhaps with a dog or cat claiming a corner. It also suits a guest room that hosts visiting couples, where a firm, stable surface pleases the widest range of sleepers.
Consider another size if...
You and your partner both move around at night, or one of you is broad shouldered, and 67.5cm each feels tight. We'd recommend the UK king instead, which gives 75cm each for two sharing; allow at least 2.7m x 2.9m for it.

How much space does each person get on a UK double Relyon Prairie 1000?
Two people sharing get 67.5cm each. That's the long standing UK standard for couples, and the firm pocket spring build helps here: each of the 1,000 springs works independently, so you feel your own side of the bed rather than every shift your partner makes.
What room size do I need for the Relyon Prairie 1000 in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows walking space on both sides and, in most rooms, bedside tables too. Measure with your wardrobe and drawers marked out before you order; the mattress itself is 135 x 190cm.
Is the UK double a good size for this mattress in a guest room?
Yes, and arguably the best one. A UK double accommodates visiting couples as well as solo guests, and the firm feel suits occasional use because it holds its shape rather than moulding to one regular sleeper. Check your spare room meets our suggested 2.6m x 2.8m minimum first.
How does the UK double compare to the UK small double for this mattress?
The UK double is 15cm wider than the UK small double, and both are the same length. For two people sharing a firm mattress every night, that extra width matters more than it sounds, since neither of you sinks toward the middle. We suggest at least 2.4m x 2.8m for the UK small double.
